(54) Hard armour panel and production method therefor


(57) The present specification discloses a method of making a hard armour panel or plate (10) including an energy absorbing ceramic tile (11) with a backing element (15) providing structural strength to the ceramic tile (11) adhered to a rear surface thereof, the method involving the steps of forming a stack of inter-leaved layers (16) of para-aramid fibre fabric interposed by thermoplastic film layers (17) conforming to the peripheral shape of the ceramic tile (11), placing the stack (15) of inter-leaved layers (16, 17) onto a rear face (13) of the ceramic tile (11) and positioning the tile and inter-leaved layers into an autoclave, within the autoclave, subjecting the stack of inter-leaved layers and the ceramic tile to a predetermined temperature and pressure regime for a period of time whereby the backing element (15) is formed into a single piece having a shape exactly conforming to the contour of the rear face (13) of the ceramic tile (11), and utilising high strength adhesive to adhere the backing element (15) to the rear face (13) of the ceramic tile.
